JARED H. PLAISTED, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF T0 H. WADSWORTH LONGFELLOW, OF BOSTON, MASSACHUSETTS.

NON-BEFILLABLE BOTTLE.

Application filed June 7, 1913, Serial No. 772,306. Renewed August 10, 1916.

To all whom it may concern Be it known that I, JARED H. PLAISTED, a citizen of the United States, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to means for preventing the refilling of receptacles such as bottles, while permitting the liquid contents of the receptacle to be quite readily poured out.

The object of the invention is to provide a simple and economically constructed nonrefillable receptacle, and one which will be durable and not liable to .get out of order.

, To these ends the invention consists in the improvements which I shall now proceed to describe and claim.

Of the accompanying drawings,

Figure 1 is a vertical sectional view of a portion of a bottle, having my improved means for preventing refilling, my improvements being shown in elevation.

. Fig. 2 is a view similar to Fig. 1, with my improvements shown in vertical section.

Figs. 3 and 4 represent sections on lines 33 and 4. 1, respectively, of Fig. 1.

Fig. 5 is a view similar to Fig. 2, but showing the parts in the position as when pouring from the bottle.

Fig. 6 is a detail section on line 6-6 of Fig. 5, but with the valve in closed position, as when the bottle is upright.

Fig. 7, in two views, shows in perspective the parts of the plug before assembling.

Similar reference characters indicate the same or similar parts in all the views.

The receptacle or bottle may be of any shape desired. The neck is indicated at 10, said neck having an internally tapered wall 11, within which is secured the plug comprising the two members shown in Fig. 7, which two members are permanently secured together, as hereinafter described, before the plug as a whole is secured within the neck of the bottle. The plug comprises a shell member 12, the bottom 13 of which is preferably internally flat, as shown, and provided with a central aperture or opening 14. The wall of the shell is recessed or slotted at opposite points, as shown at 15.

The other member of the plug comprises a disk 16, which, for convenience of description may be referred to as the cap. This Specification of Letters Patent.

Patented Mar. 27, 1911?.

Serial No. 114,290.

cap has four integral lugs 17, 17 and 18, 18. When the two members shown in Fig. 7 are assembled, as shown in the other figures of the drawings, the lugs 17 fit snugly within the wall of the shell 12, while the lugs 18 enter the recesses or slots 15, the bottoms of which, coacting with the ends of the lugs 18, determine the width of the outflow that shall exist between the upper edge of the shell 12 and the margin of the cap 16. IVhen the two members are assembled as described, they are held permanently united by a suitable cement, such as that of the nature commonly known as liquid glass. While I do not limit myself to the material of which the plug and valve shall be constructed, said material is preferably glass.

Before assembling the members of the plug shown in Fig. 17, a valve 19 is placed within the chamber so as to loosely occupy a position such as illustrated in the drawings. This valve 19 is preferably a flat disk. In any event, its lower marginal face should be perfectly flat to fit the flat face of the bottom 13 of the shell around the opening 14, and the valve disk 19 must be so constructed that it can never assume a position which will open any portion of the passage 14, excepting by a direct movement away from the bottom of the shell. In the drawings the valve is shown as a circular disk, the diameter of which is greater than that of the opening 11 and less than the internal diameter of the shell 12. Its diameter might be made somewhat less than illustrated, especially if its periphery were provided with projecting lugs, or if the inner wall of the shell 12 were provided with ribs, so as to prevent the valve from moving sufficiently laterally to expose any portion of the opening 14:-

lVith the parts constructed as illustrated in the drawings, the valve 19 will usually occupy a. somewhat eccentric position, as illustrated in Figs. 3 and 4, this being due to the fact that when the bottle is tilted to such position as shown in Fig. 5, for pouring, the valve after seating and turning the bottle upright, will remain at one side. The valve is so entirely free or movable within the chamber of the plug as to permit liquid to flow outwardly through the opening 14 .and the chamber, and through the space between the edge of the shell 12 and the mar gin of the disk cap 16, the valve either tilt- ,with a suitable cement around the outer wall of the shell 12, which wall is preferably tapering, as shown, to correspond with the taper 11 of the neck, some of said cement entering the shallow side recesses in the plug resulting from the outer edges of the lugs 18 not being quite flush with the outer wall of the shell 12, as best shown in Fig. 6. The side recesses so receiving an extra amount of cement, provide for .a more secure retention of the plug within the tapered opening.

The construction of my improved plug and valve is such that so long as the bottle is upright, or nearly so, the valve must always cover the valve seat opening, and when the bottle is tilted for pouring, the valve still remains in such position that it extends over all portions of the opening, although tilted or moved away to permit the passage of liquid between the valve seat and the margin of the valve disk. After the bottle is filled and the plug is inserted in the neck and secured there, and after the bottle has been once tilted so that the valve opens the passageway, the chamber above the valve becomes filled with liquid, which will remain there and insure that the valve will not dry out, but will stick to the valve seat. The valve can, however, be dislodged again sufliciently to pour more from Copies of this patent may be obtained for five cents each, by addressing the Commissioner the bottle, by a slight shaking while the bottle is tilted, if the contents of the bottle have been so reduced that the Weight of liquid againstthe inner face of the valve should be insuiiicient to dislodge the valve from its seat when the bottle is tilted. lVhen the contents of the bottle have been entirely poured out, there will be enough of the liquid left in the chamber, and on the valve and valve seat so that when the valve seats, the wet surfaces will cause a sort of suction between the two parts, to firmly hold the valve seat to prevent refilling, even if the bottle should be more or less. inverted and immersed, and shaken while immersed. The plain outside surface of the shell of the plug afiords ample area for the application of cement, even without the provision of any channels or recesses in the external surface of the plug.

The device is of great simplicity and low cost, because there is but one active or moving part (the-valve), and but one passage cured within its neck, said plug comprising a shell having a bottom provided with an opening, the walls of said shell having recesses, a cap having lugs secured in the recesses of the wall of the shell, said lugs extending within the shell to'form stops, and a valve loosely mounted within the chamber of the plug adapted to be limited in its outward movement by'the stops formed by said lugs. r

In testimony whereof I have affixed my signature, in presence of two witnesses.
